A FaultException is the type of exception WCF services and clients use to communicate exceptions and optionally their details.

A FaultException is the type of exception WCF services and clients use to communicate exceptions and optionally their details. Quoting from the relevant MSDN documentation page:

In a service, use the FaultException class to create an untyped fault to return to the client for debugging purposes.

In a client, catch FaultException objects to handle unknown or generic faults, such as those returned by a service with the IncludeExceptionDetailInFaults property set to true. Because FaultException extends CommunicationException, remember to catch any FaultException objects prior to catching CommunicationException objects if you want to catch them separately.

WCF/WebService: Interoperable exception handling

I understand that WCF will convert an exception into a fault and send it back as a SOAP message, but I was wondering if this is truly interoperable. I guess I'm having a tough time trying to figure out this possible scenario: Client (Java) calls a…
